Once it is determined that the female is pregnant, boost her calcium intake. The calcium is needed for strong eggshells. She will look noticeably heavier in about two weeks. She'll also be a bit sluggish.
When it comes time to lay her egg(s), the female will look for a warm, moist spot in the soil, and dig a little hole with her head. She'll lay one or two(rarely) eggs in the hole.
The eggs are the size of a thumbnail, and resemble a white tic-tac. You need to monitor closely and be very observant every day, otherwise you may never know when/if she lays the egg(s).
Caring for the eggs:
It is reccomended that you remove the egg(s) from the cage into a small incubator. A plastic container filled with soil, vermiculite, or sterile sand is best. Make sure the substrate is barely damp. Bury the egg(s) halfway in the substrate. Keep the temp in the incubator at 85F.
CAUTION: Make sure you position the eggs in the incubator, the way they were found in the cage. Rolling the egg could kill the embryo.
The egg(s) will hatch in about 40 days. The hatchlings will be 2-3 inches long. They will mature in several months, at around 5 inches. The babies won't usually eat much during the first few days after hatching because they'll still be full from the embryo they fed on while in the egg..
When they start eating, feed them wingless fruitflies, very small pinhead crickets, and things of that nature. You may also feed them some fruit puree or pure honey. They need alot of calcium to promote strong bone growth. Provide this by dusting their food with a vitamin powder that is high in calcium deposits.
